A novel combination of mutations leading to congenital ichthyosis and ichthyosis vulgaris.

Coexistence of TGM1 and FLG mutations in a newborn with congenital ichthyosis is not well described in the literature. Early genetic testing and counseling are crucial for accurate diagnosis and appropriate management. Further exploration of associated problems, including hearing loss and developmental delay, is warranted in patients with these mutations.

Adamantyl cannabinoids: a novel class of cannabinergic ligands.

Structure-activity relationship studies have established that the aliphatic side chain plays a pivotal role in determining the cannabinergic potency of tricyclic classical cannabinoids. We have now synthesized a series of analogues in which a variety of adamantyl substituents were introduced at the C3 position of Delta(8)-THC. Our lead compound, (-)-3-(1-adamantyl)-Delta(8)-tetrahydrocannabinol (1a, AM411), was found to have robust affinity and selectivity for the CB1 receptor as well as high in vivo potency.
